Coffee often be the enemy of the people with high blood pressure or hypertension, including heart disease and stroke. However, a study in the United States revealed that there was no evidence coffee may increase the risk of disease.
American Journal of Clinical Nutrition in the journal report research results after combining with previous studies, which examined the respondent 170,000 people. "The habit of drinking 3 cups of coffee a day had nothing to do with an increased risk of hypertension," said Liwey Chen, Public Health researcher from the University of Louisiana at New Orleans.
But this does not mean that drinking lots of coffee had no risk at all. The risk of hypertension for those who drank three cups of coffee a day of course is slightly different than those who drank less than 3 cups.
"In my opinion, coffee does not pose a risk of high blood pressure," said Lawrence Krakoff, researchers from Mount Sinai Medical Center, New York.
According Krakoff, the relationship between coffee and high blood pressure is difficult to explain. Thus, the effect is certainly different for each person.
Genetic background can also determine how people respond to coffee. Drinking coffee in large quantities may be safe for a person. But it can be dangerous to others.
